F NEWARK, NEW JERSEY, A CORPORATION 0F NEW JERSEY" ATOMIZER Application led September 15, 1928. Serial No.`306,148.

This invention relates to atomizers of the type adapted to be carried in the pocket, in a hand bag, or to be supported on a suitable surface.

An object of the invention is to provide a thin, compact, atomizer which can be readily carried in the pocket without danger of the liquid contents thereof leaking out or evaporating, or the parts becoming useless by reason of lodgement of dirt or dust therein.

A further object is to provide an atomizer construction in which, when the various operating elements are not in use, they are locked in such relative positions to the body thereof that they do not form objectionable Vprojections which'would catch in the clothing or in thel lining of a hand bag and tear the same. j

Further and more specific objects, features and advantages will more clearly appear from the detailed description given below taken in connection with the accompanying dra-Wings which form part of the specification, which illustrate one embodiment of the invention, and in which,

Fig. 1 is a plan view of the device.

Fig. 2 is a central vertical section on line 2, 2 of Fig. 1.

Fig. 3 is a Fig. 1.

Fig. 4 is a detail section on line 4, 4 of Fig. 2, and

Fig. 5 is a section corresponding to Fig. 2 of a modified form of the device.

As shown in Figs. 1 and 2, the device comprises a casing 10, having a removable cover plate 11 carrying the working parts of the atomizer, said cover plate being removably retained upon the casing, as by a lug 12 prodetail section on line 3, 3 of jecting into a slot in the wall of the casing and removable therefrom by springing inwardly the side wall of the casing to clear the lug. v i

Rigidly carried With the plate 11, there is shown a cylinder 13, an air pump comprising said cylinder and a piston 14 carried by a piston rod 15 sliding in a plug 16 having screw threaded engagement with the Wall of the cylinder, said piston rod upwardly terminating in a thumb piece 17 by which4 the pump` may be operated. i

j To force .the piston 14 upwardly in the cylinder 13, there is shown a compression spring 18 acting between the bottom of the cylinder and the under side of the piston 14. The bottom of the cylinder is shown as closed by'a screw plug 19, sockets 20, 21 being provided to receive a tool to unscrew the plug.

To arrange the receptacle22 for containing a liquid to be atomized, as a perfume, the plate 11 is shown as provided with a boss 23 extending above the same and having a sleeve 24 passing through the plate and extended below the same; said sleeve 24 being sui'- rounded by a stopper 25, preferably of a resilient material, such as rubber, cork or the like, which stopper is adapted to frictionally engage and close an opening 26 in the receptacle 22. Obviously the stopper element 25 may have a screw threaded engagement with the opening in the receptacle 22 if desired.

To draw liquid to be atomized, there is shown a tube 27 projecting to a point adjacent the bottom of the receptacle 22 and terminating in a no-zzle 28 above the boss 23. To atomize material drawn by aspiration out of the nozzle 28, there is shown an air conduit 29 passing through the plate 11, at 30, and so directed that air will 'cross the opening vof the nozzle 28, the other end of the tube 29 opening at 31 into the chamber of the pump, near the bottom of cylinder 13. Pressure upon'the thumb piece 17 will therefore compress air in t-he chamber of the pump which, escaping from the opening of tube 29,- will cause the atomization of liquid from the reccptacle 22.

To close the nozzle 28 when the device is not in use and to cover the working' parts upon the plate 11, there is shown a cap 32 pivotally mounted upon an axis 33 in a pair of ears 34, 35, projecting upwardly from the plate 11, the cap 32 providing a closure 36 having screw threaded engagement at 37 with thecap and having la lock nut 38 secured thereto. To press the cap 32 to open osition, there is shown a spring 39 coiled about the axis 33` and having one end pressing upwardly against the underside of the cap, as at 40,' 100 and the remaining end 41 pressing against its plate l1. Thus, there is provided an arrangement comprising the pivoted cap or member 32 which, in predetermined position, prevents passage of the liquid medium from its casing.

To hold the cap 32 in its lowered position when the device is not in use, the material of the cap is carried past the pivot 33 into alu 44, and a second lug 45 is shown carried by 51e thumb piece 17 which, in the closed position of the device, underlies the lug 44 1n which position the spring 18 being compressed and being stiffer than spring 39 lwill hold the parts in the position shown in F ig. 2.

When the thumb piece 17 is slightly depressed and revolved, the lug 45 moves substantially laterally With respect to the path of movement of the piston rod or plunger 15 whereupon cap 32 will immediately fly to open position v and the piston 14 will immediately be raised to its uppermost position ready for actuation.

To prevent accidental release of the lugs 44, 45, the lug 44 is desirably formed with downturned ears 46, 47, retaining the lug 45 against rotation when in a closed position.

To prevent accidental disengagement of the stopper 25 from the opening 26, there is shown a leaf spring 42, secured at 43 to the inner surface of the bottom Wall of the casing 10, and providing upward pressure against the receptacle 22. When the latch member 12 is released, the leaf spring 42 will lift the receptacle 22, carrying with it the cover plate 11 and the pump cylinder 13.

It is obvious that the receptacle 22, which is desirably formed of some metal as silver which will not be affected by the liquid to be atomized, may be replaced by a glass vial or the like within the spirit of the invention.

In the form shown in F ig. 4, the casing 10 has the plate 11 permanently secured thereto and the pump cylinder 13 has screw threaded engagement with said plate, forming a liquid tight joint therewith, the casing then becoming the receptacle for the liquid to be atomized, which may be filled therein as by means of a filling opening in its bottom, closed by a screw plug.

While I have described my invention in detail and with respect to a preferred form thereof, I do not desire to be limited to such details or form since many changes and modifications may be made and the invention embodied in other forms IWithout departing from the spirit and scope of the invention in its broader aspects.
